Additional Domain Controllers DNS Delegation - Prerequisite Check Failed

Question

_{Thursday, November 1, 2012 4:43 PM}

Hi Guys,

I'm busy running a lab, simulating our move to Server 2012. We will be creating a new domain.

Anyway, I have the PDC up and running, and no issues reported, but I've run into a bit of a snag. I'm adding a second domain controller, and all seems good, but the Prerequisite Check keeps failing. 

Text Description of the error:

Verification of prerequisites for Domain Controller promotion failed. You specified that you would like to create a DNS delegation in the parent zone but attempts to create the delegation failed. This could be because you do not have permissions to do so, or because the DNS Zone/Dns delegation record already exists, or because the zone is hosted by a server that does not run Windows. To ensure that this domain controller can be found by other computers on the network, you must create a DNS delegation in the parent zone for this domain. To do so, contact an administrator who is responsible for the parent DNS zone.

Here is my powershell script:

Import-Module ADDSDeployment
Install-ADDSDomainController `
-NoGlobalCatalog:$false `
-CreateDnsDelegation:$true `
-Credential (Get-Credential) `
-CriticalReplicationOnly:$false `
-DatabasePath "C:\Windows\NTDS" `
-DomainName "company" `
-InstallDns:$true `
-LogPath "C:\Windows\NTDS" `
-NoRebootOnCompletion:$false `
-ReplicationSourceDC "DC1.company.local" `
-SiteName "Default-First-Site-Name" `
-SysvolPath "C:\Windows\SYSVOL" `
-Force:$true

DC1/PDC is a DNS server, and primary NIC has it's DNS server pointing to itself. I have checked and rechecked my credentials, the PDC is Windows Server 2012, and from what I can tell, the DNS record is not pre-existing.

Please can someone be so kind as to point out what I'm missing. It's been many years since I did my MCSE. I have spent many hours Googling and browsing Technet, yet many of the threads and articles are not applicable to Windows 2012.

My primary goal with adding additional domain controllers, will be for high-availability and load-balancing of DHCP, DNS, AD and AD RMS. 

Thanks in advance for any assistance!

Hi,

Have you updated DNS delegation? Please read below article: "If installing a DNS Server, you may need to Update DNS delegation. To update, enter credentials with permission to create DNS delegation records in the parent DNS zone."
